The Double Dust Disks of HD 95086



What do other star systems look like? To help find out, astronomers are carrying out detailed observations of nearby stars in infrared light to see which have dust disks that might be forming planets. Observations by NASA's Spitzer Space Telescope and ESA's Herschel Space Observatory have found that planetary system HD 95086 has two dust disks: a hot one near the parent star and a cooler one farther out. An artist's illustration of how the system might appear is featured here, including hypothetical planets with large rings that orbit between the disks. The planets may have created the large gap between the disks by absorbing and deflecting dust with their gravity. HD 95086 is a blue star about 60 percent more massive than our Sun that lies about 300 light years from Earth and is visible with binoculars toward the constellation of Carina. Studying the HD 95086 system may help astronomers better understand the formation and evolution of our own Solar System as well as the Earth.

Okiku and the Nine Plates

The story of Okiku and the Nine Plates is one of the most famous in Japanese folklore, and continues to resonate with audiences today. There are multiple versions. In two common ones, the beautiful servant Okiku refuses to become mistress to a powerful man. He then breaks or hides one of ten precious delft plates, and tricks Okiku into believing she had done it. Losing a plate would normally be punishable by death. The man then offers her a choice; if she will sleep with him, he will not have her put to death. Virtuous Okiku still refuses. She gets drowned in a well as punishment.


In the more romantic version, which was written during the Meiji period and has clear western influences, Okiku breaks the plate herself to test the love of her fiancé. He spares her the death penalty, believing she had broken his family’s heirloom by accident. Then she reveals she did it on purpose, to test him. Enraged, he throws her down a well.


Both stories finish with Okiku becoming a ghost, forever counting the nine remaining plates. Perhaps she is still searching, perhaps she is punishing those who murdered her.

Mixing Paints



Nature is an artist, and this time she seems to have let her paints swirl together a bit. What the viewer might perceive to be Saturn's surface is really just the tops of its uppermost cloud layers. Everything we see is the result of fluid dynamics. Astronomers study Saturn's cloud dynamics in part to test and improve our understanding of fluid flows. Hopefully, what we learn will be useful for understanding our own atmosphere and that of other planetary bodies. This view looks toward the sunlit side of the rings from about 25 degrees above the ringplane. The image was taken in red light with the Cassini spacecraft narrow-angle camera on Aug. 23, 2014. The view was acquired at a distance of approximately 1.1 million miles (1.8 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 127 degrees. Image scale is 7 miles (11 kilometers) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

CDC: 172 People on Cruise Fell Ill With Norovirus


A cruise ship docked in California on Sunday after 172 people on board fell ill with the highly contagious norovirus during a nearly monthlong trip, the Centers for Disease Control and Prevention said.


Some of the more than 4,100 people aboard the Crown Princess began to show signs of the gastrointestinal sickness a few days into the voyage from Los Angeles to Hawaii to Tahiti.


The ill passengers and crew members were treated on the ship.


A CDC official was expected to board the ship to investigate the outbreak and the cruise line’s response.


The ship will undergo a deep cleaning at a terminal in San Pedro before embarking on its next voyage to the Mexican Riviera, company spokeswoman Susan Lomax said.


In April, 129 people on the same ship contracted norovirus during a seven-day cruise off the California coast. Lomax said that the ship went through the same stringent disinfecting process after it docked.
